If water quality is good then add a few more anthias to about 5 to 6 and not necessary the same. Blue eye anthias is a good choice to get other to feed. i have a purple queen, sunset, sunburst, 2 blue eye and a bartlet for more than a year. Purple queen took 2 week to start feeding only on brine/mysis shrimp while the rest on pellet. hope could help.
